Convert to replaceable idle air bleeds?

OK, so maybe I won't move the IFR ;) What cam are you running again?

First thing is to fix the wideband. Probably carbon on the sensor tip. Without the gauge, tuning is unnecessarily difficult!

The return of the dreaded flat spot may be related to t-slot exposure on both primary and secondary. My new baseplate does not have holes in the butterflies... but since I drilled my main body for bypass air, I only have to add holes to the adapter in the air cleaner stud opening.

I would try lowering it because that is really where it SHOULD be.

I'm 281/281 255/255 .620/.620 on a 105 in at 105.

I pulled the intake tonite, and tomorrow I'll look and see how my much work it is to fit that antireversion plate on it. If it's a couple of hours of TIG welding and a couple of hours of grinding, I may go for it.

If it looks like more than that, I'll put it back on and run it until next winter.

I suspect that's why mine wanted them up higher even though it shouldn't want that.

I think some of that reversion is pissing it off and keeping the IFR up seems to dampen that.

Obviously I'm guessing at what's happening, but right now, that's my working theory.
